While the State has not raised the issue, we also consider whether Hill's guilty plea waived his jurisdictional claim and conclude that it did not. A guilty plea can waive the right to appeal certain issues, such as the denial of a motion to suppress. Covin v. State, 272 Ga. App. 65, 67 (2) ( 611 SE2d 729) (2005). But even an unconditional plea of guilty cannot waive a jurisdictional issue:
Evidence also was introduced at the motion hearing that a forensic psychologist with the Georgia Department of Human Resources evaluated David prior to entry of her pleas, and the psychologist concluded that David was competent to stand trial. Finally, David's contention was called into question by the fact that at the motion hearing, David testified that she was suffering from the same anxiety and fear that she experienced when she entered her pleas, but she conceded she was able to understand what was going on at the motion hearing. Under these circumstances, the trial court was entitled to conclude that David freely and voluntarily entered pleas of guilty. See, e.g., Covin v. State, 272 Ga. App. 65, 66 (1) ( 611 SE2d 729) (2005); Smith v. State, 254 Ga. App. 832, 833 ( 563 SE2d 923) (2002); Miller, 241 Ga. App. at 398-399 (1). Finally, David appears to argue that her guilty plea on the felony obstruction charge should be set aside because there purportedly was evidence that she had a meritorious defense to the charge.
